What is Public Cloud? Everything you need to know about Public Cloud

Public Cloud is a platform that uses the standard cloud computing model to make resources remotely accessible. In this article, Vcloudia will delve into what Public Cloud is and its practical applications.

How does Public Cloud operate?

Understanding the concept of Public Cloud is quite straightforward. In its simplest terms, it represents a method of utilizing Cloud Computing technology to provide remote access to resources like virtual machines (VMs) and Storage.

When you understand Public Cloud, you'll see it as an alternative way to develop applications compared to traditional IT architectures. In a typical Public Cloud model, providers host IT resources on demand. These resources can be scaled and delivered to users through network connections, specifically over the Internet.

What are the advantages of Public Cloud?

So, what defines Public Cloud? The public cloud model incorporates various technologies, capabilities, and features. However, at its core, the public cloud possesses the following key characteristics:

- Computing utilized according to user demand.

- Easily scalable and replaceable.

- Costs based on what the user consumes.

Public Cloud service providers generally offer integrated options tailored to each customer's specific needs. They will provide more detailed guidance on what Public Cloud is and which service type best suits your requirements.

What is the structure of Public Cloud?

Public clouds are typically designed with built-in redundancy to prevent data loss. Service providers can store files in data centers (DC/DR) to ensure a smooth and rapid data recovery process during a disaster.

Understanding what the Public Cloud structure is will help you grasp its services.

So, what is the basic structure of Public Cloud? Public Clouds can be structured differently depending on the type of service they provide. Below are the three most common models available in the market today:

SaaS

SaaS is a model where the provider distributes software that is hosted on the cloud. Users access the application via the Internet. This model removes the requirement for individual users to install software on their personal machines, which reduces an organization's hardware needs and lowers support and maintenance costs.

PaaS

PaaS is a computing model that enables an organization to develop software without needing to maintain the underlying infrastructure. Essentially, the provider builds and supports an optimized environment, which is then delivered to users via a broadband connection.

IaaS

IaaS is a model in which an organization provisions its entire data infrastructure to a cloud service provider. The provider hosts everything from storage servers to network hardware and maintains environment virtualization. IaaS simplifies the use of the cloud, and the system is often more cost-effective than purchasing and maintaining hardware on-premises.

Services on Public Cloud

Beyond the fundamental service models of IaaS, PaaS, and SaaS, Public Cloud providers offer critical resources that empower modern digital operations. These include:

- Cloud Servers: These provide scalable, virtual computing power. They enable businesses to run complex applications and services without the burden of maintaining physical hardware, offering the flexibility to adjust resources as traffic demands change.

- Cloud Storage: This service offers a secure, remote, and highly available environment for data management. It ensures files are accessible from anywhere, provides robust data protection, and simplifies the process of data backup and recovery.

- Cloud PCs: This solution allows users to stream a full desktop environment directly to their devices. It enhances flexibility, facilitates seamless remote work, and ensures sensitive data remains in the cloud rather than on individual local machines.
